Abstract

Four elements model was applied to study the creep performance of corrugated box of different flute-type. The results showed that four elements model can be used to simulate short time creep of corrugated box; the instantaneous elastic coefficient of B flute corrugated box was the smallest among the 3 flute-types; the delayed elastic coefficient and glutinous coefficient of A flute corrugated box in Kelvin model were the smallest; the glutinous coefficient in Maxwell model decreases when stress level increases, which suggests obvious relativity; the relaxation time decreases obviously when stress increases; the unrecoverable permanent deformation of A flute corrugated box is the biggest; the relaxation times of corrugated box of different flute-types decreases obviously when stress increases; the decline degree of A flute corrugated box is the most obvious.
